I stumbled across a Fender PA100 on my local Craigslist for $400. A Google informed me that it is very similar to a Silverface Twin, but very little else. I'm quite fond of Twins of the Silverface Era, as I am a bit of a Jerry Garcia addict. Does anyone here own one? How does it do for classic Fender Cleans, or as a pedal platform? Are there any mods worth doing, equivalent to "Blackfacing" a Silverface Twin? In the situations when cranking it is possible (so, when using an attenuator) how does it distort?
